Table REF  summarizes the hyper-parameters we use for LVIS and COCO experiments. On LVIS, we adopt the same hyper-parameters as [1]} except for a shorter schedule (due to frozen backbone) and a background weight following [2]}, [3]} (see REF ). The hyper-parameter differences on COCO are to mitigate overfitting to the ZSD-COCO split [4]} of 48 categories, which is significantly smaller than the 800 LVIS base categories. This is necessary because F-VLM does not use other objectives e.g. knowledge distillation or weak supervision to counter-balance overfitting.
